CONTROLLING MEANS FOR DUMPING BODIES.

Application filed March 19, 1923. Serial No, 626,193.

To (LZZ whom it may concern:

Be it known that I, Join: H. HU'roHIN- soN, a subject of the King of Great Britain, residing at Port Melbourne, Victoria, Australia, have invented certain new and useful Improvements in Controlling Means for Dumping Bodies, of which the following is a specification.

This invention relates to improvements in controlling means for dumping bodies on motor vehicles or the like;

Among the objects of'the invention is to provide improved devices employed in connection with load-carrying bodies of the above character which will enable the same to be brought to dumping position quickly and easily; and which will enable the same to be returned to normal position and locked against movement in a positive and reliable manner. i

It is also an important object of the invention that the devices employed for controlling and movably supporting bodies of this character be adapted to be applied to any conventional type of vehicle.

other objects, and objects relating to details of construction, combination and arrangement of parts will hereinafter appear in the detailed description to follow.

The invention is illustrated by way of example in the accompanying drawings, in which:

Figures 1 to 6, inclusive, are similar detail views illustrating different ways of movably supporting dump bodies,

Figure 7 is a view in end elevation illustrating an improved means of this invention for looking a dump body which is movable transversely of the supporting vehicle therefor, I

Figure 11 isa detail view showing form I Like referencecharacters designate corresponding parts throughoutthe several views of the drawings.

Referring to the drawings more particularly, in Figuresl to 6, A indicates generally the bed or bottom of a movable dump body. In Fig. 1 this body carries pieces of studding B one adjacent each longitudinal edge. Ilach studding carries a plurality, of rollers E, each roller being journaled bya pin D which is supported bracket members C. In Fig. 2 the rollers E are preferably grooved as shown and the supporting means for each roller comprises a U-shaped bracket as shown. In Figuref3 the rollers F are'earried by a shaft D? and said shaft being journaled by bearing members C carried by the studs 13. In Figure 4 the rollers E are arranged inpairs and each pair journaled by a suitable bearing C carried upon the bottom face of bed A. In Figure 5 channel rails G are provided which rotatably support rollers E adapted, to movably support bed or body A, and in Figure 6 rollers E areformed to co-opcrate with inverted channel members H to mov ably support the body or. bed A.

In Figure 7 the body supporting side member A is movably supported by rollers upon rails carried by a motor vehicle or "the like and these rails extend transversely of the motor vehicle. In order to lock the body in its receiving position, I provide the twolink members-J each comprising. two bars as shown in Figure 9 which are connected at a point intermediate their ends, as at K, and

each link has one end M pivotally connected to the body A and its remaining end L similo'y'a pair of.

larly connected to the associated rail by a pin N, said pin N being preferably secured by a chain as shown. In utilizing this an rangement the links J when connected as shown prevent movement of the body and the body can be easily released by removal of pins N.

In Figure 8 there is shown two castings 0, each of which is of the shape best shown in Fig. 10. The casting may be secured at the forward end of a vehicle upon which a body is longitudinally movable; and each casting is formed with a longitudinally extending passageway I adapted to receive the depending flange 0 of a body supporting side member 0 Fig. 10.

Each casting O is formed with an upstanding projection X which forms a stop for limiting forward movement of the associated dump body and also provides a fulcrum for a bar in starting the dump body rearwardly upon the associated vehicle. Each casting carries a locking pin Q which may be shifted longitudinally by a lever B. Each pin. Q, is adapted to move into the associated passageway P, transversely thereof. and enter opening 0 in the end of the associated body supporting member 0 and thereby lock the body against movement. Each lever B- is fulcrnmed as shown in Figure 8, and its one end suitably connected as at S to a rod T whereby said pins Q may be shifted from looking position. The rod T carries a collar V and between this collar and a casting 0 there is interposed a compression spring ll whereby to hold the pins Q in locking position. Also each casting O carries an elongated pl ate member which is pivotally supported for swinging movement as shown in Figure It) and which is drawn by spring W to move into the path of the associated pin Q. Upon the rod T being operated to move the pins Q for releasing the dump body the member IV will move into position to prevent return move ment of pins Q, and thus upon the members 0 being returned into passageways P with force the members IV will be engaged and moved to permit the pins Q to assume their locking positions with relation to the associated dump body. In Figure 10 it will be observed that wheels or rollers E movably support the dump body supports upon rails B. Between the rear ends of these rails there is secured a plate A which carries a hook member A positioned centrally with respect to the ends of the plate. Also the plate A may rest upon the supporting plate B of the associated vehicle. In Figure 11 there is shown in section a frame member of a dump body which is arranged longitudinally of the body and carries a pair of prongs G which sup ort therebetween a pin D The member 8 should be pivotally attached to the frame members of dump brackets Il body, as indicated in Figure 10. With the rearward movement of the dump body the pin D carried thereby will engage the hook A and tip the body so that the same may assume its dumping position.

In Figure 15 there is shown a motor vehicle, and upon the chassis frame of the same there is supported apair of rails G by The bracket members may be of the form shown in Figure 12 or of the form shown in Figure 13. Reinforcing members L may be employed and these members, together with the brackets, may be secured to the chassis frame by bolts K Channel rails G may be employed upon which the body may be movably supported as illustrated. The forward end of the dump body may have connected thereto the one end of a cable R and the other end of the cable secured to a drum ll The shaft carrying drum M may have associated therewith a ratchet wheel U and pawl T and also a bracket member 0 for turnably supporting, in conjunction with rails G a shaft N said shaft N carrying a pinion in mesh with a cog wheel carried by shaft carrying drum M The shaft N may be provided with a crank as shown for manually rotating and thereby controlling movement of associated dump body. Also the shaft N may carry a brake drum P which may have a brake band operatively associated therewith and the lug Q formed upon the bracket employed for securing the brake band in an obvious manner.

As is obvious from Figure 15 the drum M and associated operating means may be an ployed for returning the dump body to its normal position after the same has been tipped to its (lumpin position.

A tail gate 5 may be employed for the dump body and this gate may have connected thereto the one end of a cabled which may be controlled by a suitable drum 2 and hand lever 23. Also a prop S may be provided which has its one end pivotally secured to one of the rails G and its other end adapted to be brought to engage the dump body as shown.

I also find it desirable to employ a jack V which is hinged to the rear end of the motor vehicle chassis as shown and adapted to be swung to a vertical and operative position. The jack has its base IV preferably rounded, and one end of a cable X is connected to the lower end of the jack. The other end of this cable is secured to an eye Y and this may be engaged with a hook Z and thereby to hold the jack V in its nonoperative position. Also ramps 6 may be employed for elevating the forward end of the vehicle and these ramps when not in use may be suspended in any convenient manner for the vehicle, as indicated at 7,

It is thought from the foregoing description, taken in connection with the drawings referred to, that the construction and operation of the different cont-rolling devices of this invention may be clearly understood. It has been found that these devices can be used in a highly eflicient manner to advantagein controlling a dump body when it is desired to discharge the load therefrom.

It also should be pointed out that the dump body of vehicle supported as shown and described herein could be entirely removed from the supporting tracks of the vehicle and moved upon other tracks provided therefor. In this way the body' of the vehicle could be moved to a place for unloading in an easy manner.

Having now particularly described and ascertained the nature of my said invention and in whatmanner the same is to be performed, I declare that what I claim is 1. In combination, a movable body having a pair of protrusions at one end, a pair of locking members one for each protrusion and each locking member having a socket adapted to receive the associated protrusion and associated locking member having transverse openings adapted to be brought into registering relation, spring pressed pins adapted to enter said openings and thereby lock the movable body against movement, and combined rod and lever means whereby to simultaneously move said pins to a reeasing position with respect to said protrusions.

2. In combination, a movable body having a protrusion at one end, a locking member having a socket for receiving said prol'rusion, said protrusion and locking member having transverse openings adapted to be brought into register, a spring pressed member adapted to be normally disposed in register with the openings in said locking mem ber and be moved from this position by pressure from said protrusion upon the movable body, and a locking pin adapted to be inserted in the openings of the locking memher and opening in the protrusion of the movable body when said openings are brought into register.

3. In an apparatus of the character described, a pair of rails, a wheel-supported body movable upon said rails, a plate extending between said rails' and disposed therebeneath, means for securing the plate to said rails, a hook formed upon the plate at a point central to the length thereof and upon the upper face of said plate, and means carried by the movable body adapted to engage with said hook.

4. In combination, a removable body having a protrusion at one end, a locking memher having a socket for receiving said protrusion, said protrusion and locking member having transverse openings adapted to be brought into register, a yieldable member adapted to be normally disposed in register with the openings in said locking member and also adapted to move from this position by pressure from said protrusion upon the movable body, and a locking pin adapted to be inserted in the openings of the locking member and opening in the protrusion or movable body when said openings are brought into register.

5. In combination, a vehicle, a jack having its one end pivotally connected to the end of said vehicle and adapted to be swung into position for supporting the associated end of the vehicle, and a rounded groundengaging member carried by said jack andadapted to facilitate the movement of said jack into its operative position with respect to said vehicle.

6. In combination, a vehicle chassis, rails supported thereby, a body movable upon the rails.'an upstanding casting at the inner end of said rails with relation to the movement of the body, said casting having a slot in the forward face thereof, a protrusion carried by the vehicle body adapted to enter said slot when the vehicle body is brought into proper position with respect to the casing, and means adapted to automatically engage the protrusion carried by said body when within the slot of the casting and lock the body against movement.
